Hi all,

I am trying to instrument https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Compiler.java

I am using the following code:

ClassPool cp = ClassPool.getDefault();

CtClass ctClazz = cp.get("clojure.lang.Compiler");

ctClazz.addMethod(CtNewMethod.make("public String foo (){return \"foo\"; }", ctClazz));

return ctClazz.toClass();

I am calling getDeclaredMethod on the returned class and invoke on the method to call foo() which throws:

IllegalAccessError tried to access class clojure.lang.Compiler$DefExpr$Parser from class clojure.lang.Compiler  clojure.lang.Compiler.<clinit>

(Compiler.java:102)

Javassist's docs state that it does not work with inner classes, which I suspect to be the problem here.

Or rather it could be a ClassLoader problem. Unfortunately I know little about classloaders.

Any pointers would be appreciated.

Thanks!
